His declaration permits propane shippers from other states to drive more hours, which "will help get propane companies resupplied so Ohioans who use propane to heat their homes can stay warm," Kasich said.
More than 14 million families across the U.S. use propane to fuel their furnaces, according to the Propane Education & Research Council.

"Propane customers in the Upper Peninsula should use their propane supplies wisely in the coming weeks by reducing usage and avoiding energy waste," Michigan Public Service Commission Chairman John Quackenbush told NBC affiliate WILX on Monday.

However, the energy shortage is not just a result of families and business owners trying to keep buildings comfortable during the persistent cold spells.

"Propane prices in the Midwest will likely need to rise to keep propane in the region," according to the EIA.
In the middle of January, average propane prices across the nation were 58 cents per gallon higher than the same period last year, EIA reported.
